Role of string-like collective atomic motion on diffusion and structural relaxation in glass forming Cu-Zr alloys.

Abstract

We investigate Cu-Zr liquid alloys using molecular dynamics simulation and well-accepted embedded atom method potentials over a wide range of chemical composition and temperature as model metallic glass-forming (GF) liquids. As with other types of GF materials, the dynamics of these complex liquids are characterized by "dynamic heterogeneity" in the form of… (More)
